An Apple Watch tracks your heart rate, workouts and sleep, and can call for help after a hard fall. The right model depends on whether you want everyday health tracking, a bigger screen, or a rugged watch for long days outside.
Our top pick is the Apple Watch SE 3 in the 40mm size. It covers the core health and fitness features for a lower price, and it is the model reviewers most often point to for most people. The other picks cover the Series 12 for a bigger screen and brighter display, and the Ultra 4 for rugged outdoor use and the longest battery.

The Apple Watch SE 3 40mm is our pick for most people, because it covers the health, safety and fitness basics at a lower price than the rest of the range.
The SE 3 gives you sleep score, cycle tracking, sleep apnea alerts and fall and crash detection, which is a solid health and safety set for everyday wear. Its 40mm aluminum case is a comfortable size for many wrists, and it charges to 8 hours in 15 minutes. Reviewers note that the same processor as the Apple Watch 5 gives it a considerable performance boost over the Series 3, and it works with Siri AI.
The SE 3 has no always-on display and no ECG monitor, and its 18-hour battery trails the 24-hour Series 12 models. Its 8GB internal memory in the GPS model is a concern for some reviewers, since it can make updates harder.
If it's not for you, the Series 12 suits buyers who want a bigger screen or longer battery and HRV tracking, while the Ultra 4 suits serious outdoor athletes who need multi-day battery life and satellite messaging.
Reviewers consistently describe the SE line as the best value entry into the Apple Watch range. You get the core health tracking and safety features most people use, without the cost of the premium models.
The 40mm size suits smaller wrists, and the 18-hour battery covers a full day with workouts.





If you want a larger watch face and a fuller health dashboard, the Series 12 46mm adds size and the newest health tracking for a higher price.
Prices and availability on Amazon change often.
The Series 12 is the choice if you want the full health dashboard and a bigger screen. The readiness score and HRV tracking are features reviewers rate highly for daily use.
Choose the 46mm if you prefer a larger face; the 42mm suits smaller wrists.





The Ultra 4 is built for rugged use, long runs and multi-day battery. It also adds satellite emergency messaging for areas without signal.
Prices and availability on Amazon change often.
Reviewers recommend the Ultra line for hikers, runners and anyone away from signal. The dual-frequency GPS and long battery make it the most capable watch in this list.





A smaller, lower-cost Series 12 option for buyers who want the newest health tracking in a compact case.
Prices and availability on Amazon change often.
For smaller wrists, the 42mm Series 12 gives the full health feature set without the larger case.





The same rugged Ultra 4 with a titanium Milanese Loop band for a dressier look.
Prices and availability on Amazon change often.
If you want the Ultra 4 but prefer a metal band for everyday wear, this version keeps the same features.
Most people should start with the SE 3. Choose the Series 12 for a bigger screen and the full readiness dashboard. Pick the Ultra 4 if you train outdoors or need the longest battery.
If you have an iPhone and only need basic tracking, the SE 3 is enough. An older discounted model is a sensible buy if the newest feature is not important to you.
The SE 3 40mm is the best for most people. It covers the core health and safety features at a lower price.
Yes. You need an iPhone to set up any Apple Watch.
The 40mm suits smaller wrists and lighter use. The larger size gives a bigger screen.
The listings do not describe blood pressure monitoring, so we do not recommend it for that purpose.
Ultra models support cellular calls on the GPS + Cellular version, which needs a carrier plan.
